The filter in the wall unit has the main responsibility for trapping really small dust parts and other miniscule particles from the air in the house. The filter can both help keep the wall unit from building up too much dust and make it operate more efficient while, at the same time, filtering the air in your home. During regular maintenance the filter should be swapped out for a new one or possible scrubbed clean periodically depending on how much you use it.
Main clues the primary air filter is in dire need of a replacement
- The main filter looks bad and probably should be replaced ASAP
- Manufacturers have recommended to replace the filter four times a year to assist in keeping the indoor air clean and fresh
- If you were to lift up the filter, the light is unable to penetrate through a very dirty air filter
